DEVICE FOR SHAPING AND SETTING TUBES.

:EEEGIFIGATION forming part of Letters Patent No. 740,239, dated September 29, 1903. Application filed Au usta, 1902. Seria1Nm118l583. (Nomnsieh) To all whom, it ind/y concern:

Be it known that I, SAMUEL E. CONDON, a citizen of the United States, and aresident of New York, Brooklyn borough, in the county of Kings and State of New York, have invented certain new and useful Improvements in Devices for-Shaping and SettingTubes, which improvements are fully set forth in the fol-' lowing specification.

This invention relates to improvements in mechanical structures of that class extensively employed for the purpose of fianging, beading,or shaping tubes formed from yield-- ing material and for the purpose of setting such tubes or producing between each of the same and a part cooperating therewith, as the tube-sheet of a boiler, a sealed or tight junc struction whereby accurate and speedy ad justment of the working parts may be efiected, which shall be constructed-in a manner to facilitate repairing operations and the ready substitution of serviceable parts -for those becoming worn or defective through use or otherwise, and which shall possess certain well-deiined advantages over prior analogous structures.

The invention consists in the employment of certain parts novel as to form, in the novel disposition and arrangement of the various parts thereof, in certain combinations of the latter, and in certain details of construction, all o'fwhich will be specifically referred to hereinafter and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings, wherein similar reference-numerals denote corresponding parts throughout the several views, in which Figure 1 is a front-end view of a device for shaping and seiting tubes constructed in accordance with my invention. Fig. 2 isa side elevation of the device, certainof ,the movable parts thereof being shown relatively in i position for service, and to better illustrate the practical application of the device as a whole there is shown in connection therewith and in central longitudinal section a portion of a boiler-tube. Fig. .3 is a transverse section taken along the line a a of Fig. 2. Fig. 4 is a transverse section taken along the line b h of Fig. 2. Fig. 5 is a fragmentary sectional view illustrating the cooperative relation of certain minor elements of the device and the positions assu med thereby in service. Fig. 6 is a central longitudinal section taken along the line Ct at of Fig. 1, the parts being released from their locked position as'shown in Fig. 2. Fig. 7 is a central longitudinal section taken along the line b h of Fig. 1. Fig. 8 is a view illustrating in side elevation the tool-head impeller which I purpose employing as an element of my improved device. Fig. 9 is a view in perspective, illustrating certain features of construction of the toolhead which I make use of. in perspective, showing one of the tool-slides whichl make use of detached from the general construction. Fig. 11 is a face view of the gripper-block which constitutes an element of' my improved device, said block being shown detached from-the general construction. r In a general sense myinveution comprises an axial element or spindle, means for temporarily fastening one end of said spindle within the end portion of a tubular object, so that said spindle when thus disposed will accurately coincide or register with the longitudinal axis of such tubular object, a toolhead adapted to be impelled to and fro with respect to the longitudinal axis of said spindie, and means for thus impelling said toolhead. r

It further comprises a tool-head, a tool conjoined with and movable to and fro ina plane parallel with the axis of said head'and independent-1y thereof, a controller situated away from said tool, and a member interposed between said controller and said tool and supporting the latter for service.

In practice, and particularly where it is desired to utilize the device in the shaping and setting of objects such as boiler-tubes, it is Fig. is a view a portion of the device may be securely locked temporarily within the tube or object to be acted upon and in such manner that the longitudinal axis of the device as a whole will coincide or aline with the longitudinal axis of such object, and in the accomplishment of this result, reference being bad to the accompanying drawings, the spindle 2, gripperhead 2, grippers 2, and gripper-block 3 are directly concerned.

The grippers 2 are suitably spaced circumferentially of the head 2, are arrangedfor movement simultaneously and uniformly therealong, and are adapted when duly moved in service to effect a binding or looking force between the head 2 and the surrounding wall of the tubular object (indicated in the drawings by the numeral 3) in connection with which the device is being used.

The grippers 2 may be of any suitable form in cross-section and are here shown as being arranged to undergo each a sliding movement length wise with respect to the head 2, said grippers being let into suitable channels, one in each channel, formed at the circumferential portion of the head 2 and each extending lengthwise therealong. The base of each of the channels containing the grippers 2 is inclined or beveled lengthwise, and the bottom of each gripper is accordinglyinclined or beveled, so that at all times in service and irrespective of the position occupied by any of the grippers relatively to its containing-channel and of the movements of said grippers, respectively, along their containingchannels the outer or gripping surface, ordinarily serrated or otherwise roughened, of each gripper 2 will remain parallel with the longitudinal axis of the device as a whole, and accordingly with the longitudinal axis of the tubular object in connection with which the device is being used, and the grippingsurfaces of the several grippers may accordingly be caused to simultaneously and uniformly approach and likewise recede from the interior wall of such tubular object by duly moving said grippers jointlyin theircontaining-channels. Each of the channels in which work the grippers 2 is provided with a lateral groove coextensive with the length of the channel, and each of said grippers is provided with a lateral tongue which takes into the groove of its containing-channel, this construction being employed to prevent displacement of any of said grippers radially away from the head 2. The important characteristic of each of the channels containing the grippers 2" is its inclined base, an inclined surface being accordingly provided, along which a cooperating gripper moves in operation, and while I prefer to provide material at the opposite sides of these inclined surfaces whereby channels for containing said grippers may be secured and which serves to guide said grippers each in itsmovements along its cooperating inclined surface it will be understood that other means for thus guiding the grippers 2" may be availed of.

I purpose employing for the grippers 2" channels conforming in all essential details to the channel illustrated in Fig. 9 of the drawings, save that the latter will not ordinarily have an inclined base and is provided to contain a part, ordinarily one of a series of like parts, which will be described hereinafter. For cooperation with the grippers 2 I provide the gripper-block 3,the same being here shown in the form of a disk having suitably-spaced radially-elongated openings 4 and firmly adjusted to the spindle 2 in advance of the head 2. I have shown the block 3 as having a threaded engagement with the spindle 2, and any suitable means, as the check-nut 4', may be employed for holding said block against movement independently of the spindle, the said check-nut being situated still in advance of the block 3. Where the construction thus far described is employed, it will be seen that longitudinal movement of the spindle 2 in one direction with respect to the head 2, the latter being held stationary, will result in the grippers 2" being withdrawn each partially from its containing-channel away from its locking position and through the medium of the block 3 and pins 4", all as indicated in Fig. 6, while a reverse longitudinal movement of said spindle will result in said grippers being urged to their locking position between the head 2 and the object being acted upon, as indicated in Fig. 5 of the drawings, and through the medium of the block 3, which now abuts against the adjacent ends of the grippers.

The gripper-head 2' is provided with an extension 5, on which is loosely mounted a toolhead 5, said tool-head being ordinarily capable of movement both longitudinally and rotarily with respect to said extension.

In connection with the head 5 any suitable tool or series of tools may be employed. In this connection, however, I have shown a series of headers 5" let into pockets 6, one in each pocket, at the front end of the head 5. Each of the headers 5 is held in position for service within its containing-pocket by means of an axial element (5, on which the beader rotates in service. The elements 6 are shown in the accompanying drawings, each in the form of a bolt extending radially inward through the adjacent pocket 6 and tapped into the head 5.

The headers 5" are suitably contoured exteriorly to engage and bead over outwardly the adjacent end of the tube 3 when the head 5 shall have been duly urged or impelled longitudinally along the extension 5 in the direction of the tube 3 and thereafter rotated on the extension 5. i

- For urging the tool-head 5 longitudinally along the extension 5, as above stated, I employ an impeller 6", adapted to be operated by means of a turning-bar, wrench, or the like. This impeller by'preference approximates the form of an enlarged nut, has a threaded engagement with the extension 5, as illustrated in the drawings, and the head 5' occupies a position along the extension 5 in advance of said impeller. I further purpose interposing between the head 5 and the impeller 6" an antifriction-washer or analogous element 7, the function of which will be explained hereinafter.

While I have shown the impeller 6 as being provided with recesses 7, suitably spaced circumferentially thereof and designed each to receive an operating or turning bar, said impeller may be formed many-sided to permit the use of a wrench or analogous implement in connection therewith, if desired.

. Where the construction under consideration is employed, it will be observed that through the medium of the impeller 6 when properly manipulated or rotated in one direction on the extension 5 a substantial direct impelling force will be exerted upon the head 5', thereby causing the latter to move longitudinally along the extension 5 until the headers 5" shall have been brought firmly into engagement with the adjacent end of the tube 3, whereupon the user inserts into one of the recesses 7", formed in the head 5' and suitably spaced circumferentially with respect thereto, a turning-bar or analogous device and rotates the head 5, thus producing a beading eilect upon the adjacent end of the tube 3. As the heading operation thus progresses the headers 5 may be kept in due contact with the tube 3 by properly manipulating the impeller G, as will be clearly u nderstood, and in this connection the antifriction-washer 7 permits the head 5 to thus rotate without af-' fecting the impeller 6". Also the impeller 6" may be held against rotaiive action while the head 5' is being rotated by means of the turning-bar used in connection therewith, and the adjustment of these parts, the impeller 6", and head 5 with respect to the ex tension 5 is such as to permit speedy operation thereof by direct hand-pressure when desired.

It is desirable that means be employed whereby the head 5' shall be caused to accompany the impeller 6" in the latters receding actio'n along the extension 5 and at the same time permit rotative action of either of the parts 5' 6 each independently of the other,

and in this connection acoupling of any suitable and approved availed of.

For the attainment of the foregoing purpose I have shown a collar 8, screwed onto the rear end of the head 5 and interiorly shouldered, so that it may be firmly seated on said head. This collar may be formed in anysided or otherwise, as with openings 8', to permit the use in connection therewith of a suitableimplement-asawrench,turningbar,

construction may be or the like-for adjusting'the same tothe I head 5. A pin 8' extends radially inward through the collar 8 and engages the annular recess 8 with which the impeller 6" is provided, the recess 8 being clearly shown in Fig. 8 of the drawings. If deemed advisable, a plurality of pins 8 may be employed for the purpose specified.

Here it maybe pointed out that the action of the spindle 2 with respect to the head 2 and whereby the grippers 2" are caused to move into a locked position or the position in dicated in Fig. 2 of the drawings is efiected and controlled by means of a part conjoined with said spindle, which part is here shown in the form of a nut 9, threaded to the spindle 2 at the rear end thereof and abutting against the rear end of the extension 5 under the locked condition of the parts now under consideration, the head 2, with its extension 5, accordingly serving as an intermediate member between said grippers and the nut 9.

To release the parts just referred to from their locked positions, it is only necessary to reversely move the nut 9 somewhat and thereafter still'further directly move the impeller 6", which, as the headers are now firmly in contact with the tube 3, will result in the headQ being withdrawnsomewhat from the tube 3, and accordingly from its locked relation with respect to the grippers 2", thus 1ib crating the latter from their grasp on the tube 3.

In some instances it is desirable to subject the tube 3' to an operation whereby the same 7 shall be partially expanded or flanged, as indicated in Fig. 5 of the drawings, such operation being preliminary to the final beading operation, whereby the setting of the'tube as to the tube-sheet 9 is effected.

To the foregoing end I purpose making use of a tool-slide 9", adjusted to the head 5 so as to be movable to and'fro longitudinally therealong. The slide 9" terminates at its front end in two opposing members, between which is mounted to rotate, as on the axial element or pin 11,'connecting said opposing elements, a primary-tool ll of any suitable general contour, though here shown'as con ical. The form of the tool 11' and its disposition with respect to the slide 9" may be modified to suit varying requirements,- as will be fully understood. The. slide 9 is provided atits rear end with an elongated member 11', whose bottom surface by preference coincides with the bottom surface of the slide 9",

and the member 11" terminates at its distant end in an upturned stop or offset 12, the rear end of said slide proper accordingly approximating the character of a shoulder opposing'the oftset 12, and the same is indicated by'the numeral 12. The conjoining of the slide '9 with the head 5" may be effected in any approved manner, though I purpose providing said head with a channel for the reception of saidslide, as clearly illustrated in Fig. 9. Specifically, its rear,'thus forminga shoulder 13, and the collar 8 accordingly engages-the reduced por- I reduce the head '5 at tion of the head at the rear end thereof.

he channel 12 is formed at the circumference of the head 5, runs parallel with its axis, and is coextensive with both the main and reduced portions thereof. As will be observed, the channel 12" is out of registry with any one of the beaders 5 and is provided to contain for longitudinal sliding movement the tool-slide 9. To this end the channel 12" is provided with a lateral groove 13, and the tool-slide 9 is accordingly provided with a lateral tongue 3', taking into said groove, all as clearly illustrated in Figs. 9 and 10 of the drawings.

13 is a controller, here shown as arranged for direct hand operation and whereby the slide 9 may be duly controlled in its movements along its containing-channel12. The controller 13" in this instance approximates the general form of an enlarged annulus and when the parts are assembled is disposed for rotative movement on the reduced portion of the head 5 between the shoulder 13 and the collar 8 and traversing the member 11 between the shoulder 12 and the offset 12, the said member 11" accordingly lying between the controller 13 and the reduced portion of the head 5', with its offset 12 engaging said controller at the rear thereof.

In assembling the parts now under consideration the member 11 of the slide 9 is first duly adjusted with respect to the controller 13", whereupon the said slide is inserted into the channel 12", at the rear end thereof, and is accompanied by the controller 13", which latter as the slide 9 progresses along its containing-channel in due course finds its bearing on the reduced portion of the head 5. The foregoing is permissible, as the channel 12" at the reduced portion of the head 5 corresponds, substantially, with the thickness of the memberll", so that the outer surface of the latter will not ordinarilyproject-beyond the circumferential surface of the reduced portion of the head 5'. The operative relation existing between the controller 13 and the slide 9" is such that a partialrotative movement imparted to the former in one direction will result in the latter being urged forwardly along its containing-channel adistance sufiicient to bring the tool 11 partially in advance of the adjacent header or headers 5 for pre-- liminary action on the tube under treatment, as indicated in Fig. 5, and like movementof said controller in the opposite direction will result in said slide being reversely moved along its containing-channel to a point in the rear of the adjacent header or headers 5", as indicated in Fig. 2. Accordingly I have shown the controller 13 as being provided at its front face with a depression whose working surface 14: or a substantial portion of which surface is beveled or inclined, so as to act on the shoulder 12 after the manner of a cam, and accordingly impart to the slide 9 a movement forwardly-along its containingchannel when the controller 13 is partially rotated in one direction, as hereinbefore stated. The depression aforenamed is preferably formed so that one wall thereof will lap along the slide 9" atone side thereof, and thus limit the reverse rotative movement of the controller 13 in the practical operation of the device. The controller 13 is provided at its rear face and immediately opposite the working surface 14 with a depression whose working surface 14 is beveled or inclined uniformly with the surface 14, said working surface 14 being provided to act on the offset 12 after the manner of a cam and accordingly cause the slide 9 to undergo a reverse movement upon a reverse movement being imparted to the controller 13". In other words, the working surface 14 engages at all times the rear end of and urges the slide 9" forwardly, and the working surface 14 effects a return movement of said slide accordingly as the controller 13" is partially rotated in opposite directions. The depression last referred to is also formed by preference so that one wall thereof is adapted to be engaged by the offset 12, and consequently limit the direct rotative movement of the controller 13 in the practical operation of the device.

It will be understood that a plurality of tool-slides 9 may be arranged for cooperation with the head 5 and controller 13, the said head being channeled accordingly, the adjustment of each tool-slide with respect to the controller 13 being such as already described and said controller being provided with working faces 14. 14 at each segment thereof cooperating, respectively, with the said toolslides, all as clearly indicated in the drawings. In this connection the tool-slide channels of the head 5 conform each to that denoted by the numeral 12 and are located one channel midway between neighboring headers 5", so

that the several channels may be uniformly.

spaced circumferentially of the head 5. Accordingly the controller 13" serves as a universal controller for the slides 9, and when rotatively moved it transmitsa sliding movement simultaneously to the several tool-slides, as will be readily understood.

It will be seen that my improved apparatus for shaping and setting tubes, whose operation will be apparent from the foregoing description thereof, is Well adapted for the purposes for which it is intended, and, further, that the same may be modified to some extent, particularly as regards the form of the impeller 6", the form of the controller 13, the means employed for guiding the toolslides 9 in operation, the means employed for guiding the grippers 2" in operation, and the details of the general construction, without materially departing from the spirit and principle of my invention.
